i want to model 3 method heat transfer with eachother free convection radiation and conduction help me please fluent 5.2

dear teta,

can you discribe you problmes more detail?? by the way, free convection due to conduction can be handle by FLUNET (v6) very well.

tyw

hi i want to model free convection between some shield ,prevent radiation heat transfer , so my problem should contian modeling convection ,radiation and conduction ,and i have fluent v5.2 . please explain for me what options i should active , i experirnced many methods and i tried to study thier theoritical basis but i could not get good results . please help me.

thank you .

my FLUENT version here is 6.0.2. Inside its documentation got one example just very similiar with you problem. you may need to go through the tutorial..

Hi dear friend :

thank you for paying attention .

Would you please , example I studied in fluent 5.2.3 has such situatiobn I wanted , but some unrael condiotns was in it , for example gravity was set 5e-5 in it well it converged after some itterations but it would not give good answer when I increase gravity . would you check these parameter in it .
